To all whom it may concern:

Be it known that I, HENRY F. LANGRE- DEE, a citizen of the United States, residing at 11923 Halsted street, Chicago, in the county oi' Cook and State of Illinois, have invented a new and usel'ul Improvement in Dum -l/Vagons, of which the following is a speci cation.

My invention relates to certain new and useful improvements in dump wagons and is fully described and explained in the specification and shown in the accompanying drawing, in which:

Figure 1 is a top plan oi my improved wagon with the sides and ends thereof removed; Fig. 2 is a transverse section in the line 2 of Fig. 1; Fig. 3 is a longitudinal section in the line 3 of Fig. 2; Fig. 4 is a front elevation of the Wagon and Fig. 5 is a `front elevation of a modified form of the wagon showing the plate shifting mechanism.

Referring to the drawings A is a series o'l' transversely extending holsters which are connected by longitudinally extending sills A1 at the two sides oi the wagon-bed. At the 'front and rear of these sills are placed end-gates A2 of sheet-metal, the said endgates extending transversely of the wagonbed from side to side and in a vertical direction 'from the holsters to a height oi' about one-third of the desired wagon-box. Upon holsters A are placed castings B each of which comprises curved track portions l) one to each side of the center and two diagonally disposed bottom sup orting webs b1 which meet at an angle centra ly disposed with respect to the holsters. The track portions t are curved upward to meet the diagonally disosed bottom supporting portions blto a'l'lord strength to the same and they are also mutually connected together by portions t2 lying upon the corresponding bolster so that a single rigid unitary casting is provided. One ol the castings B lies just inside oi the 'liront end gate A2 as illustrated, another is centrally disposed upon the medial bolster A in the preferred form of construction although if desired other medial castings and medial bolsters could be provided, and the third lies just inside the rear gate A2. Upon the diagonally disposed bottom supporting portions oi the castings B are supported two diagonally disposed bottom-plates C which slope downwards from a central-longitudinal line of the wagon to lines slightly more than half of the distance from the center of the wagon-body to the sides thereof, the edges of the said bottom-plates being elevated a slight distance above the track portions l) ol' the castings B as illustrated. Upon the track portions b of the castings B are carried movable bottom j plates D running upon rollers d which hear upon the track portions b, the said plates being capable of being drawn inward laterally on said track portions to positions underneath the central stationary bottom-plate O as illustrated in dotted lines in Fig. 2. Rollers c are provided on the castings B at the outer ends of the diagonally disposed portions b1 thereof to give a substantially frictionless bearing to said movable bottomplates as they are drawn in.

In order to complete the wagon body sideboards E are placed upon the sills A1 and secured to these side-boards are end boards Fj" which lie just inside the end-gates as illustratcd in dotted lines in Fig. 3 and are notched out to rest upon the diagonally disposed bottom-plates C, the lower edges ofthe end-boards heilig just above the level of the laterally movable bottom-plates D.

It will be seen that when the wagon-body so constructed is loaded with loose material such as is commonly placed in dumpingwagons, the body can very readily be evacuated by drawing in the movable bottom plates D to the position shown in dotted lines in Fig. 2. Such lateral movement of the bottom platos can be performed without any substantial raising of the load, the only force which needs to be overcome being the friction of the load on said plates. When the plates are drawn into this position a very wide dumping space is provided at each side ol the wagon and the slant of the central or stationary bottom plate C is such as to cause the material situated thereover to roll by gravity downward to the dumping spaces as provided.

The preferred means for causing the lateral movement of the plates D is illustrated in F igs. 1 to 4 from which it will be seen that a rock-shaft F extends longitudinally of the wagon-bed, the same passing through the castings B and the end-gate A2. On the lront ol'l the said rock-shalt is mounted the disk F1 connected by links f with the outer lateral edges of the shiftable bottom-plates D and at the rear of the rock-shaft is mounted a cross-bar F2 similarly connected by links f to the shill table bottom-plates as illustrated. A hand-lever F3 is provided, the same being secured to the rock-shaftF and having means for securing it to the periphery of the disk F1 whereby the shaft may be rocked. Thus when the lever F3 is moved te the right as viewed in Fig. 4 the links will be drawn together and the shiftable bottom-plates rel I sides of the wagon-body and resting upon tracted underneath the diagonally disposed and stationary bottom-plates to dump the contents of the wagon.

In the modified form of construction shown in F ig. 5, the wagon-bed construction including the shiftable and. stationary bottomplates is identical with that shown in the other figures. The rock-shaft is also arranged as in the other form of construction and is provided with the same disk at its forward end and the same rocking lever. rEhe rock-shaft is, however, provided at its front and rear ends with sprocket-wheels over which run sprocket chains f1 which in turn pass over idlers f2 suitably supported by the wagon-bed. rlhe chains are attached by clips f 3 to the shiftable bottom-plates so that when the shaft is rocked the bottom-platos will be moved in and out by the said sprocketchains instead of the links f as in the form of construction already described.

l realize that considerable variation is possible in the details of construction oi my improved device, without departing from the spirit of my invention, and l do not intend therefore, to limit myself to the specific form herein shown and described.

What l claim as new and desire to secure by Letters Patent, is

1. The combinationwith the sides and ends of a wagon-body of two stationary bottomplates sloping laterally downward. from a centrally disposed longitudinally extendingline, two movable bottom-portions at the sides of the stationary portions and extending therefrom to the si'des of the wagon-body, and means for sliding said movable bottomportions laterally inward beneath said stationary bottom-portions.

2. The combination with the sides and ends of a wagon-body of two longitudinally extending stationary portions slanting laterally from a longitudinally extending centrally disposed line within the wagon-body, tracks ruiming beneath saidstationary portions and extending to the sides of the wagonbody, two movable bottom-portions running upon said tracks extending from the stationary bottom-portion to the sides of the wagon-body and means for drawing said movable bottom-portions beneath the stationary portions to dump the contents of the wagon.

3. The combination with a series of transversely extending bolsters of side and end portions of a wagon box, tracks resting upon said bolsters, longitudinally extending stationary bottom-portions sloping laterally downward from the line centrally disposed sar/,40a

with respect to the sides of the wagon and terminating inside the sides of the wagon to leave spaces between their outer edges and sides of the wagon, laterally movable bottomportions underneath said stationary bottomportions and extending therefrom to the said tracks and means for moving said movable bottom-portions laterally beneath the stationary portions to dump the wagon.

et. The combination with transverse bolsters of the sides and. ends of a wagon, castings mounted upon said bolsters and each comprising track-portions and diagonally disposed portions overhanging the trackportions and sloping downward laterally from centrally disposed points on said bolsters, stationary bottom-portions secured to the angularly disposed portions of said castings whereby they are given a lateral slope downwards in two directions from a central line of the wagon-body, movable bottomportions resting upon the track-portions of said castings and means for drawing said movable bottom-portions beneath the stationary bottom-portions to dump the wagon.

The combination with the sides and ends of a wagon of two stationary bottomportions sloping downwards laterally in opposite directions from a centrally disposed line running longitudinally of the wagonbody, two longitudinally extending and laterally movable bottom-portions extending outwards from the outer edges of said stationary bottom-portions to the sides of the wagon, a rock-shaft extending centrally of the wagon, and means of connection between said rock-shaft and said laterally movable bottom-portions whereby the rocking of the shaft will draw said portions together beneath the stationary members of the bottom to discharge the load.

6. rllhe combination with the sides and ends of a wagon of stationary bottom portions sloping downward laterally from a longitudinally extending centrally disposed line within the wagon-body, two movable bottom-portions extending inward from the sides of the wagon to points underneath the outer edges of the stationary bottom-portions, a rock-shaft extending longitudinally of the wagon-body, links having eccentric connection with the rock shaft and connected at their opposite ends to the movable bottomportions whereby the rocking of the shaft will draw said portions together beneath the stationary bottom-portions and means for rocking said shaft.
